First, Randal defines god as a "necessarily existent, non-physical agent, who is omniscient, omnipotent, and perfectly good." This is the basic god of classical theism which I think was a good idea for Randal to define upfront so there's no confusion. The only problem I have of course is the "necessarily existent" part. I know that many classical theists view god as necessarily existent, but there is often an attempt to define god into existence this way that I think is little more than wordplay. Thankfully, Randal does not try to make that argument for god in this debate.
Randal outlines his three main arguments:
- Rational belief in god doesn't require evidence
- God is a legitimate philosophical explanation
- God best accounts for the cognitive faculty of moral intuition
Let's go over them one by one.
1. Rational belief in god doesn't require evidence
Randal first defends the idea that rational belief in god doesn't require evidence. He tries to argue that it is properly basic, much like the belief in an external world. "One need not have evidence for god to believe rationally that god exists," Randal declares. He later says, "Belief in god can be produced in conditions which qualify it as properly basic." He tells the story about a non-religious Canadian rock musician who walked into a church in New York one day and was "struck by overwhelming spiritual presence." But so what? As Randal himself observes, "Millions of people have formed belief about god with the same naturalness and immediacy, the same phenomenology of self-presentation that [the Canadian rock musician] experienced." In other words, millions of people have formed belief in other gods as well as non-gods as a result of spiritual experience. There is no special power Christianity has in the spiritual domain.
